MOF Siltation study, Bonny River, Nigeria
Determination local wave and current climate, 2D hydraulic modelling, estimation of sedimentation and erosion rates
M.W. Kellogg Ltd
Bonny River, Nigeria
The existing Nigerian Liquid Natural Gas Plant at Bonny Island is to be extended. As part of the extension a new Material Off-loading Facility is to be constructed.
This study assessed the risk of siltation/erosion near the NLNG plant site, specifically the area in front of the NLNG slot and the slot itself, the area around the two loading platforms (one existing and one to be constructed) and the existing material off-loading facility (MOF).
The hydraulic and morphological study focused on
- the determination and interpretation of the local wave and current climate,
- an estimation of the morphological consequences of the projected development,
- the determination of hydraulic conditions near the loading jetty protruding into Bonny River,
- the stability of the river section in which the jetty is constructed.
Numerical modelling using the FINEL package was applied to make quantitative assessments of the hydraulic conditions and the sea bed development.
